[ Upstream commit 064970a0aae978073a859aaf0793bfe14762d4f3 ]

Secondary DAI in Exynos I2S driver is not used by any of the currently
supported boards and it causes problems due to some limitations in the
ASoC code. Disable it until it gets proper support both by board-specific
and ASoC core code. Also disable IDMA support, which relies on secondary
DAI presence.

This patch fixes following kernel warning:
samsung-i2s 3830000.i2s: ASoC: Failed to create component debugfs directory
samsung-i2s 3830000.i2s: ASoC: Failed to create component debugfs directory
